Rapid and numerous advances in medical science are keeping us alive longer and helping us deliver the next generation of healthy babies. A new report from the UN Department of Economic and Social Affairs projects that the world's population is going to continue to boom, with the worldwide population projected to reach 9.7 billion by 2050. The projection also indicates the population will top 8.5 billion by 2030.
Fertility rates are down in almost every region of the world, yet the ever increasing life expectancy is still allowing population growth continue to increase — albeit with an increasingly older populace.
That being said, many of the resources our survival here on Earth depends on are finite. Conversations on how to sustain those resources with some semblance of equity are paramount to our ability to accommodate such a big population increase.
In 2013, famed British naturalist David Attenborough scathingly expressed his feelings on the population boom, telling The Radio Times that humans are a plague. Adding the warning that "Either we limit our population growth or the natural world will do it for us." He cites climate change as one such factor that will limit humanity's time on Earth if trends are not changed.
Regardless if the situation is as dire as Attenborough and Hawking believe, increasing Earth's population while refusing to focus on better sustainability practices is a recipe for catastrophic global disaster.
